Cooling device

ABSTRACT

The present invention relates to a cooling device, which has a central heat conductor with a plurality of cooling fins extended on the periphery of the central heat conductor and a hollow chamber formed therein, provided with an agitator and filled with a cooling liquid. At least a transparent window is disposed on the cooling device for observing the internal condition of the chamber outside the cooling device and ascertaining if the agitator operates smoothly, so as to observe the cooling module, maintain the normal cooling function thereof and prevent the problem that electronic component is fried due to excessive heat accumulation caused by poor heat dissipation. Meanwhile, a lamp is employed to irradiate lights onto the transparent window and the lights are refracted by water waves of the agitated cooling liquid inside the chamber to exhibit a flashing effect.

FIELD OF THE INVENTION

The present invention relates to a cooling device, and more particularlyto one with structure of which can observe a cooling module and maintainnormal cooling function thereof at any time, prevent electroniccomponent from being fried as a result of excessive heat accumulation,and exhibit special flashing effect by using water waves to refract lamplight.

BACKGROUND OF THE INVENTION

As shown in FIG. 1, a conventional cooling module structure includes acooling device 10, a holder 20 and a cooling fan 30, in which thecooling device 10 is directly contacted with a heating electroniccomponent to absorb its thermal energy, the cooling fan 30 is fixedlydisposed on top of the cooling device 10 by using the holder 20 insupport of thermal energy dissipation.

The cooling device 10 has a central heat conductor 11, which has aplurality of cooling fins 12 extended from its periphery and a hollowchamber 13 that is formed therein and absolutely airtight. The chamberhas an agitator 14 disposed therein and is filled with a cooling liquid,which is possibly water, a condensing liquid or other liquid capable ofabsorbing thermal energy and providing phase transformation between gasand liquid.

The corresponding positions of the agitator 14 and the cooling fan 14are provided with magnetically coupling elements 15, 31 respectively.

Therefore, when the cooling fan 30 rotates, the agitator 14 is driven bythe magnetic attraction of the magnetically coupling elements 15, 31 tosynchronously rotate with the cooling fan 30, so as to chum the coolingliquid filled in the chamber 14 and achieve a faster cooling effect forhigher temperature.

Whereas, the chamber 13 of the conventional cooling module is a roomthat is absolutely airtight; instead of being directly coupled with anddriven by the cooling fan 30, the agitator 14 is driven by the magneticattraction of the magnetically coupling elements 15, 31. As aconsequence, the condition inside the chamber 13 is hardly aware byobserving the cooling device 10 externally, and there is no way todetermine if the agitator 14 is smoothly operated.

If the agitator 14 is not smoothly operated, the condensing liquidfilled in the chamber 13 is in a still state. Moreover, after absorbingthermal energy, the thermal energy is unable to be uniformly distributedto each cooling fin 12 by convection. Hence, the overall cooling effectis greatly lessened, adding that heating electronic components could befried due to excessive heat accumulation caused by poor heatdissipation.

SUMMARY OF THE INVENTION

In view of the foregoing concern, the present invention thus provides acooling device to tackle a variety of problems existing in theaforementioned structure.

The cooling device of the present invention has a central heatconductor, which has a plurality of cooling fins extended from itsperiphery and a hollow chamber that is formed therein and is absolutelyairtight. The chamber has an agitator disposed therein and is filledwith a cooling liquid, and a transparent window is disposed on thecooling device, such that the internal condition of the chamber can beobserved outside the cooling device and whether the agitator is smoothlyoperated can be also aware. Accordingly, the cooling module can beobserved at any time and its normal cooling function can be secured, soas to prevent the problem that electronic component will be fried due toexcessive heat accumulation caused by poor heat dissipation.

Besides, the present invention employs a lamp to irradiate its light onthe transparent window, making the light exhibit a flashing visualeffect while the light is subject to the refraction of water waves ofthe agitated cooling liquid inside the chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention relates to a cooling device. Given theillustration of FIG. 2 and FIG. 3, the cooling module at least includesa cooling device 10, a holder 20 and a cooling fan 30, in which thecooling device 10 is directly contacted with a heating electroniccomponent to absorb its thermal energy, the cooling fan 30 is fixedlydisposed on top of the cooling device 10 by the holder 20 to supportthermal energy dissipation.

The cooling device 10 has a central heat conductor 11, which has aplurality of cooling fins 12 extended from its periphery and a hollowchamber 13 that is formed therein and is absolutely airtight. Thechamber has an agitator 14 disposed therein and is filled with a coolingliquid, which is possibly water, a condensing liquid or other liquidcapable of absorbing thermal energy and providing the phasetransformation between gas and liquid. The corresponding positions ofthe agitator 14 and the cooling fan 14 are provided with magneticallycoupling elements 15, 31 respectively. Therefore, the agitator 14 isdriven by the magnetic attraction of the magnetically coupling elements15, 31 to synchronously rotate with the cooling fan 30, so as to chumthe cooling liquid filled in the chamber 14 and achieve a faster coolingeffect for higher temperature.

As illustrated in FIG. 4, the present invention provides at least atransparent window 40 disposed on the cooling device 10 and enabling anobservation of the chamber 13 outside the cooling device 10. As such,the internal condition of the chamber 13 can be directly observedthrough the transparent window 40 and whether the agitator 14 operatesmoothly can be aware, such that the normal function of the coolingmodule can be maintained at any time and the problem that electroniccomponent is fried due to excessive heat accumulation caused by poorheat dissipation is prevented.

The transparent window 40 of the present invention can be made of glass,acrylic or any transparent material with light-transmitting effect, canbe colored or colorless, and can be in form of a plane, a convex or aspecial embossing pattern.

As shown in FIG. 5, a lamp is disposed on a proper position of theholder 20 or the frame of the cooling fan 30, and the light of the lamp21 is irradiated onto the transparent window 40 and is refracted bywater waves of the agitated cooling liquid inside the chamber 13 toexhibit a flashing effect. More particularly, when the transparentwindow 40 is in form of a convex or a special embossing pattern, therefracted lights are scattered in all directions to generate a bettervisual effect.

In sum, from the above-mentioned characteristics those features not onlyhave a novelty among similar products and a progressiveness but alsohave an industry utility.
